1 Claim.

This invention relates to a type chase or the like for use in connection with a printing machine of the class employing a pigmented tape against which the type is stamped to produce an embossed monogram or printing impression upon an article.

An obj ect ofthe invention is to provide a simple formof thermostatic control device'which will enable the use in connection with a printing machine or monogrammer, of certain manufactured metallicor pigment tape that will, to produce the embossed impression, release at a given ltemperature. Y

A further object is to provide for the purposes describeda thermostatic control Set at the temperature necessary to correlate with the metallic or pigment tape of any special manufacture so as to effect thereby a clear release and make a per- Arect impression, and further to provide a control which, when set, will not Vary more than two degrees Fahrenheit.

Still another object of the invention is to so combine the thermostatic control with a type .carrier that the type, irrespective of outside temperature, will be maintained-in synchronized relation to the tape at that temperature which will produce the vbest impression, and further that there will be no overheating of the type under any condition, thereby entirely eliminating the danger of damaging the work.` The device of 'my invention makes it possible for an amateur or beginner to successfully perform embossing'operations, and it eliminates entirely the necessity of making a fewpractice impressions in order to gauge the heat of the type with relation to the release of the tape, preparatory to making the embossed impression. Y

A still further object of the inventionr is to provide a type carrier having constructional features so combinedA and arranged as to permit interchangeability of thermostatic units in order that, where different kinds of special tapes are to be used, there `can be selected and applied a 4thermostatic control which is set at the temperature best suited to release a given tape.

With the foregoing and other objects in View,

the invention consists, of the novel constructiom combination and arrangement of parts asv hereinafter more specifically described, and illustrated in the accompanying drawing, wherein is shown a practical embodiment of the invention as reduced to practice. f f

In the drawing, wherein like reference characters denote correspondingparts throughout the several views: ,i

Figure 1 represents a fragmentary top plan view and section of a type chase, showing the tubular thermostatic unit disposed in a bore;

Fig. 2 is a front elevational view of the type carrier showing the condenser unit, with the face plate omitted; Y

Fig. 3 is a cross section taken on the line 3-3 of Fig. 2, showing the arrangement of the thermostatic unit, the heating element and condenser with relation to the type elements; and' Fig. 4 is a diagrammatic plan View showing the circuit connections for the thermostatic unit,V

condenser and heating cartridge unit, the lastnamed being shown in section. n

For the purpose of illustration, I have shown my present invention as applied to a type chase or carrier of the reversible type, employed in and constituting a feature or" the improved printing` and embossing machine illustrated and described Y type, on the operation of the machine, is brought into contact with the metallic or pigment tape to stamp the work. It will be recognized, however, that the thermostatic unit with its condenser and controlled heating cartridge unit may be utilized and combined with any suitable or approved type-holding or Vcarrying body.

In the exemplification shown, 10 denotes in general a fragmentary portion of a-type lchase or carrier the body 11 of which consists of a bronze casting or thelike, this casting being produced at one corner with an integral elongated enlargement 12 which projects well above the face 13 oi the body and also extends beyond they plane of the end 14 thereof; formed a groove l5 for receiving the type dies or elements 16, this groove being formed between a clamping slide 17 and the opposing inner Side 18 ci the enlargement 12. The clamping slide 17 is mounted for adjustment upon the face 13 (as illustrated and described in my copending application above referred to) so as to clamp the type elements 16 against the side 18 which suitably serves as a rigid abutment wall for this purpose. As illustrated in Fig. 1, the enlargement- On the face 13, there isj v12 and type groove 15 extend entirely across the .body 11 in parallel relation.

Provided Within the enlargement 12 and eX- tending from end to end thereof in parallel res lation with the type groove 15 is a bore'19 in .whichA is, centrally disposed a cylindrical thermostatic engage at a contact point 26.
